According to BabyNames.com, the name Grace is Latin, meaning "charm." But as Irwin shared in her Instagram post, the reason they chose the name goes deeper than that, and pays homage to both sides of little Grace's family. "Our graceful warrior is the most beautiful light," she wrote in the post, adding, "Grace is named after my great-grandmother, and relatives in Chandler's family dating back to the 1700s."

As for baby Grace's middle name, well, the famous couple actually chose two for their first born, with Irwin explaining, "Her middle names, Warrior Irwin, are a tribute to my dad and his legacy as the most incredible Wildlife Warrior." Sniff. No, you're crying!

Even the sweet newborn's last name was shared with a sweet sentiment from Irwin, with the exuberant new mom writing, "Her last name is Powell and she already has such a kind soul just like her dad."
